香港科技大学设计世界上首个3D人工眼球—防生眼（希望尽快用于临床）

香港科技大学设计的世界上首个3D人工眼球——EC-EYE仿生眼，被称为“人眼Plus”，其后侧的纳米探测器密度达4.6亿个，其是正常人眼感光细胞密度的四十余倍，且能在19.2毫秒内响应并生成电流，反应时间不到人眼的一半，通过信号转换后，计算机能识别电信号并成像。回答下列问题

（1）EC-EYE仿生眼由前部的铝壳和后部的眼窝对接形成球形腔体，其内充满离子液，模仿玻璃体，设备前部的双凸形镜头模拟 晶状体 ，后部感受光信号刺激的纳米探测器模拟 视网膜 。 （2）镜头与纳米探测器之间的距离可调节，看远处时距离将 变长 ；纳米探测器（直径几微米）将获得的信号进行传输、转换后形成图像输出，而人体形成视觉的部位是 大脑皮层视觉中枢。 。 （3）EC-EYE仿生眼利用类似太阳能电池中的电化学反应，将光能转化为电能维持运作，无需外部电源。而在人体中，感受光线、传递信号等各种生命活动都需要 呼吸 作用提供能量。 （4）目前EC-EYE仿生眼还不够完善，无法广泛应用于临床，请你提出两条改进建议： 降低成本、镜头的曲度要可调节（或让感光设备直接与大脑连接生成物像、缩小液态金属丝直径与纳米检测器对接，提高分辨率、优化离子液组成，使光在液体中传播更高效（减小折射）、增加夜视和红外功能等）（转载：百度题库

The EC-EYE bionic eye, the world's first 3D artificial eye designed by the Hong Kong University of Science and Technology, is known as the "Human Eye Plus". Its rear side has a density of 460 million nano detectors, which is more than 40 times the density of normal human photoreceptor cells. It can respond and generate current within 19.2 milliseconds, with a response time less than half of that of the human eye. After signal conversion, the computer can recognize electrical signals and image them. Answer the following questions (1) The EC-EYE biomimetic eye consists of a spherical cavity formed by the connection of an aluminum shell at the front and an eye socket at the back, which is filled with ionic liquid and mimics a vitreous body. The device features a dual convex lens at the front that simulates a crystalline lens, and a nano detector at the back that senses light signal stimulation to simulate a retina. (2) The distance between the lens and the nanodetector can be adjusted, and the distance will increase when viewed from a distance; Nanodetectors (with a diameter of a few micrometers) transmit and convert the obtained signals to form image outputs, and the part of the human body that forms vision is the visual center of the cerebral cortex. (3) The EC-EYE bionic eye utilizes electrochemical reactions similar to those in solar cells to convert light energy into electrical energy to maintain operation without the need for an external power source. In the human body, various life activities such as sensing light and transmitting signals require energy provided by respiration. (4) At present, the EC-EYE bionic eye is not yet fully developed and cannot be widely applied in clinical practice. Please propose two improvement suggestions: reducing costs, adjusting the curvature of the lens (or directly connecting the photosensitive device to the brain to generate object images, reducing the diameter of liquid metal wires and docking with nanodetectors to improve resolution, optimizing the composition of ionic liquids to make light propagation more efficient in liquids (reducing refraction), increasing night vision and infrared functions, etc.) Written on Monday, January 7th, 2025
